My workload has been roughly the same throughout, but from this week will increase dramatically.
I have been working on a rota 2-3 days per week but the school day was extended 7:30-6 with no breaks whatsoever - lunch eaten with the children, playtimes supervising the children.
I set 4 hours of work each day for those at home, and marked what was submitted, which was about 50%, on my days working from home.
I set up a dedicated email address to support parents, and a group chat to support pupils. Messages each day were in the dozens (parents) and hundreds (children). On days at home I answered pretty much immediately 24/7, and on days I was in school I had to do those during the evening.
On weekends those messages didn't stop and I answered them.
During holidays I continued my days in school, even though teachers aren't paid for holidays, but only set fun activities and there was no marking. Contact from parents stopped but messages from pupils still needed answering.
Now I am back at school full time teaching Year 6 - but planning must be done on evening Zoom PPA meetings as no PPA in school time.
But I also need to continue planning work for my own Year 3 class, marking submitted work, replying to those dozens/hundreds of daily messages that come through 24/7.
